What is Building Permit Tor Bor 1 in Thailand?

The Definition

In Thailand, Building Permit Tor Bor 1 refers to the official government-issued construction permit used to authorize the building of a structure, typically issued under Thailand’s building control framework by the local authority or competent municipality. In practical property transactions, it is one of the key documents buyers, lenders, and lawyers check to confirm that a house or building was lawfully approved for construction and matches the approved plans. For Thai property buyers, this permit matters because it helps verify that the structure is not an illegal build and reduces the risk of future enforcement, demolition orders, or financing problems.

The Thai Legal Context

Thailand’s building-permit process is governed by the country’s building control laws and local administrative authorities, with permits typically handled through the relevant municipality or local government office rather than the Land Department. While the provided sources do not quote the permit form name in full, they do confirm that a buyer’s legal due diligence should include reviewing building permits alongside title deeds, zoning, and planning compliance before purchase. In the Thai market, this is especially important because a property can have a valid title deed yet still have an improperly approved or non-compliant structure, which is a very different risk profile from many Western markets where buyers often assume title and building legality are bundled more closely together.

The Thailand-specific issue is that foreign buyers are often focused on ownership form—condo freehold, leasehold, superficies, or company structures—while overlooking the legality of the improvement itself on the land. Foreigners generally cannot own land in Thailand, though they can own condos within the foreign quota and may own buildings or structures in certain legal arrangements; however, the building still must be properly permitted and compliant with Thai regulations. Common friction points include discovering that the house was extended without approval, the permit does not match the as-built floor area, the land use or setback rules were violated, or the buyer must spend additional money on legalization, redesign, or retroactive approvals before a bank will finance the property or before a future resale can proceed smoothly.
